In 2025, Humboldt Park School celebrated the major construction of their Green & Healthy Schoolyard—in this space previously dominated by impervious asphalt. Through a three-year, multi-phase process, students, community members, partners, and other stakeholders worked together to design this project and raise funds to make their shared vision real. This intentionally holistic approach resulted in green infrastructure for stormwater management, outdoor education spaces, enhanced recreation amenities, and a revitalized schoolyard that fosters curricular connections, play, and a deeper connection with nature.
Humboldt Park School’s greener, healthier schoolyard manages approximately 182,275 gallons of stormwater per rain event.
